This is much too simplistic an answer. I suggest both of you read UPDATING and the handbook. In short, it's guaranteed only when the kernel is built from the same sources from which world was built. If you've cvsup'd or otherwise updated your source tree, you should follow the directions in UPDATING, or risk odd behavior of ps, top and other things. It may often do no harm, just like passing on a blind curve. But you should never build world *after* building the kernel. -- Barney Wolff http://www.databus.com/bwresume.pdf I'm available by contract or FT, in the NYC metro area or via the 'Net.
